Failure Prediction in a Layered Shell
Application ID: 48371
Laminated shells made of carbon fiber reinforced polymer (CRFP) are common in a large variety of applications due to their high strength-to-weight ratio. The widespread attention to laminated shells is due to their diverse applications in aerospace, marine, automotive, and various manufacturing industries. It is necessary to evaluate the structural integrity of a laminated shell for a set of applied loads in order to make the design of such structures reliable.
In this example, the failure indices and safety factors for a stack of shells (laminate with ply orientation of 90/-45/45/0) are compared with a NAFEMS benchmark solution. The example demonstrates the use of the Shell interface for building layered shells as well as the Safety feature for predicting failure for a set of applied loads.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products.
